ofrei's site is confusing. I think they are used to dealing with a clientele that doesn't interface them via the web. I had a parts question the other day and instead of answering via email (how I contacted them) they asked that I call them.

All I know is based on hard work & writing by others. I can only aspire to augment this body of knowledge. If I am wrong it is because of my own failings. -me
